of san francisco. for years before i joined the board of supervisors i served on with many volunteers the community advisory group to the central subway. with countless volunteers from the bay view, from visitation valley, from mission bay, south of market, union square, and of course thousands of residents and leaders from chinatown who went to countless public meetings provided tens of thousands of signatures, and stood for years to work extremely hard for world class transportation into the heart of our city, but we know we are building the central subway not just based on our history but for our future. by the year 2040 we will have 100,000 new households and 200,000 new workers and thousands of new daily car trips. we have to prepare for the future. let me close with a couple of quick thoughts.
